Metal Seals for Strapping/Banding
25mm x 57mm Lapover Metal Seals for Steel Strapping
Lapover metal seals are a proven, widely used way to secure steel strapping around loads for storage and transport. This product is a 25mm x 57mm lapover metal seal designed for use with steel strapping/banding systems where a dependable mechanical joint is required. When correctly applied with the appropriate sealing tool, the seal helps lock the strap in place so tension is maintained and the load stays consolidated.
These seals are commonly selected for industrial packaging tasks where steel strapping is preferred for its strength and resistance to abrasion. They are suitable for general strapping operations across warehousing, manufacturing, and distribution environments, and are typically supplied in bulk quantities for efficient day-to-day use.
Key Features
Lapover seal design
A standard lapover style seal that is applied over overlapped steel strapping to create a secure joint when crimped with the correct sealer.
For steel strapping/banding applications
Designed specifically as a metal seal for strapping/banding systems where steel strap is used to bundle, unitise, or reinforce loads.
25mm x 57mm size
Manufactured to a 25mm width with a 57mm length, matching common requirements for 25mm steel strapping set-ups.
Tool-applied closure
Intended to be closed using a compatible sealing tool (commonly a single-notch sealer for lapover seals), helping deliver consistent closures in repetitive packing operations.
Bulk supply for operational efficiency
Often purchased in larger pack quantities to support ongoing strapping needs in busy packing stations.
- Standard lapover metal seal for steel strapping/banding

- General warehouse and manufacturing strapping operations
25mm x 57mm Lapover Metal Seals — Full Product Guide
Choosing the right seal is essential for safe, reliable strapping. The seal is the mechanical connection that holds the strap overlap together after tensioning. This guide explains what lapover seals are, how they are typically used, and what to consider when selecting and applying them in a steel strapping system.
How It Works
A lapover seal is placed over two overlapping layers of steel strapping. After the strap is tensioned around the load, the seal is positioned at the overlap and then crimped using a compatible sealing tool. The crimping action deforms the seal and grips the strap layers, creating a locked joint intended to resist slip under load.
In a typical workflow, the strap is first tensioned with a tensioner, then the seal is applied and crimped, and finally the strap is cut. Correct tool selection and correct application technique are key to achieving a consistent closure.
Materials and Construction
These are metal seals intended for use with steel strapping/banding. Metal seals are commonly chosen for steel strapping systems because they are designed to deform under tool pressure and bite into the strap surface, helping to maintain tension and reduce the risk of joint movement during handling.
Strapping System Compatibility
This product is specified as a 25mm x 57mm lapover seal. In practice, lapover seals of this size are used with 25mm steel strapping systems. Always match the seal to the strap width and to the sealing tool type recommended for lapover seals.
Tooling note: Lapover seals are commonly used with a single-notch sealer designed for the relevant strap width. Using the correct sealer helps ensure the seal is crimped properly and consistently.
Health and Safety
Steel strapping systems operate under high tension and should be handled with care. Follow site safety procedures and tool manufacturer guidance. As a general rule:
- Wear appropriate PPE (for example, hand and eye protection) when tensioning and sealing steel strap.
- Keep hands clear of the seal and strap path during tensioning and crimping.
- Use only compatible tools in good condition to reduce the risk of poor seals or strap recoil.
- Dispose of cut strap ends safely to avoid sharp-edge injuries.
Ideal Applications and Use Cases
Lapover metal seals are widely used in industrial packaging where steel strapping is selected for strength and durability. Typical use cases include:
- Pallet reinforcement: adding stability to palletised loads during transport.
- Bundling: securing multiple items together for easier handling.
- Heavy or rigid products: where a robust strapping system is preferred.
- Warehouse and distribution: repetitive strapping tasks where consistent closures are required.
Maintenance, Cleaning and Care
Metal seals themselves are consumable items, but overall performance depends heavily on correct storage and tool condition:
- Store dry: keep seals in a clean, dry area to help prevent contamination that could affect sealing consistency.
- Keep tools maintained: inspect sealers and tensioners regularly; worn jaws or misalignment can lead to weak or inconsistent crimps.
- Use the right seal every time: mixing seal types or sizes within a packing station can cause application errors.
Case Study (Typical Scenario)
A warehouse shipping mixed industrial goods uses steel strapping to stabilise pallet loads that may be handled multiple times in transit. By standardising on a consistent lapover seal size for their 25mm steel strapping set-up and ensuring operators use the correct sealer, the team can achieve repeatable closures and reduce rework caused by incorrect sealing.
Who is it for?
- Warehouses and distribution centres using steel strapping for pallet stability
- Manufacturers bundling products for internal movement or outbound shipping
- Packaging teams that need a standard lapover seal for routine strapping operations
